Clinical and Volumetric Changes Following Single Pontic Site Development Using Multilayered Platelet Rich Fibrin Versus Connective Tissue Grafting in the Maxillary Esthetic Zone

Sponsor: Cairo University

Summary

In clinical practice most patients' first concern is esthetics, soft tissue grafting is becoming routine in clinical practice to make up for the deficiency in supra-crestal tissue dimension that typically follows tooth loss. The edentulous site experiences major qualitative and quantitative changes because of a number of sequential events that occur after tooth extraction. Ridge dimensional alterations of the underlying bone and the soft tissue architecture overlaying it are the consequence of the socket healing process. To maintain the remaining teeth, aesthetic jaw support and optimal food chewing, lost teeth must be replaced. The teeth adjacent to and opposing a missing tooth will eventually tip, shift, and migrate, disrupting normal function. One integral part of the new strategy for treating periodontal diseases is thought to be surgical periodontal operations. Soft tissue grafting has become more frequently utilized to improve the aesthetics of teeth and dental implant sites by treating mucogingival abnormalities, restoring an appropriate width of keratinized tissue, and enhancing tissue thickness. SCTG has its own limitations, such as lack of graft availability, need for a second surgical site, proximity to palatine neurovascular complex and unaesthetic tissue contour at the recipient site. Due to these limitations, investigations on more regenerative nature techniques have been explored such as PRF, Using PRF instead of SCTG has the added value of decreasing discomfort and postoperative pain after the surgical procedure due to having additional donor site, To the best of our knowledge testing multi-layer PRF against SCTG in pontic site augmentation was never done before.
